Sole for footwear



FIG. 1 is a left side view of a sole for footwear, showing my new design;

FIG. 2 is a bottom view thereof; and,

FIG. 3 is a perspective view thereof, seen from the front and right side.

The broken lines showing the sole throughout the views, illustrates the environment in which the design resides, and forms no part of the claim. 

I claim the ornamental design for a sole for footwear, as shown and described.
